The intelligent control system of urban traffic based on GPRS

The intelligent control system of the urban traffic with data share mode was set up in this paper. The information of the urban traffic was collected by ARM, and the data was processed fuzzy and unitary, and the common data were transmitted to the net of the urban traffic by GPRS. So the data of the intelligent node in the network are shared. Every intelligent node can work independently, and also can be centralized controlled and managed by network control computer. Intelligent manage of the urban traffic has been carried out. Efficient and safe traffic has been ensured. A design of the intelligent node were presented, the communication protocol to the net of urban traffic was put forward.
